. To all whom it may concern:

Be it known that I', HORACE S. CLARK, a

citizen of the 'United States, residing in Los Angeles, -county of Los Angeles,'and State ofl California, have invented a certain new and useful Improvement in BrakeeI-Iangers, of which the following is a specification.

This invention relates to hangers .for brake shoes, and has for its object to rovide'means for automatically taking upt e Wear. of the bearings or'pivoted connections of the hanger chattering of the and to thereby rake shoes: With the ordinary hanger, as is well known,

. when thebearing of the hanger pivot in the support o'r in the brake shoe becomes worn a very objectionablenoise is caused by the ratbracket, .hanger and brake shoe with a portion of a car Wheel; and Fig. 2 is a view showi '30 ing lthe pivoted hanger bearings -in Vtransverse section. f

As shown in the drawing,`the dev iceis de signed more particularly to befapplied .to

street lcars or electric cars, but it is obvious that vthe invention is lalso applicable to any and .all kinds of railway or other vehicles.

, For. the purpose of il ustration, .the hanger is shownas formed of two' similar partsl or lhanger bars 3 and 4, each having atapered or conical bearing 5 projecting at each end and adapted toturn/in oppositel tapered sockets 6 in the bracket 7 and a so in the,

brake shoe or head 8.

-A bolt orl pin 9 passes through a' central opening in each bearing and carries a spring 10 of the desired strength, which constantly tends to force the tapered hanger bearings into theconical sockets andautoinatically take up all the wear of the pivoted joint. The bracket lmay .be supported from the car i framell in any convenient manner.

If desired, the two parts of the 'hanger may be made interchangeable and reversible.' As the 4conical ,fjhearing of the hanger in either the bracket or the brake head wears prevent the objectionable.

socket, the hanger bars having conica the spring acts automatically to draw the ta. pered portion of the hanger 4farther into the socket and thereby prevent any looseness of the lparts of the joint, while at the same time theanger is prefectly free to swing and does not bind at the pivots. By this means all rattling or chattering of the brake shoes is avoided and .a very simple A and eflicient justs 'itself automatical y and requires butlittle attention'or repair Having now described my invention, what I clai-m as new and desire to secure by Letters Patent is bars, one having a conica projection, a ta-` pered socket forming a bearlng for said projection, and a springnormally acting to force theconical ro'ection into said socket.

2. A bra e anger, comprising a support or bracket having a tapered socket or bearing, two hanger bars, one on each side of the beartion for enga ing-said soc et, and a spring normally tenin'g toforce the conical projection into the socket.' v

3. A brake hanger, co Iprising a su port or bracket having a tapered socket or ear- .bearing,'a brake head having a `ta ered ro'- jections for engaging said sockets, and sprmgs sockets.

4. A brake hanger device, comprising a fixed bracket element, and a swinging element formed. of a pair of hanger bars, one of these elements having opposite rigid tapered of t e other element, and means for automatieallytakin up the wearof the bearings.

5. A bralre hanger device, comprising a fixed bracket element, and aswinging element formed of a pair of hanger bars, oneof these elements having -opposite rigid tapered projections bearing in corresponding sockets gether.

6. A brake hanger, comprising two hanger bars each having a conical projection or bear- .7. brake hanger, ,comprising two similar hanger construction isl rovided which .ad

1. A brake hanger, com 'rising two hanger ing, one of said bars havina conical projecof the other element, anda 'spring mechanf' ism for forcing the parts of the bearings toing, two hanger bars, one onach side of the for normally forcing said projections into the pr'ections bearing in corresponding sockets ing at one end, oppositely tapered. sockets, l and a spring for forcing said bearings intoth'e ings7 and a spring on said bolt j brake head.

9'. A brake 'hanger device, com rising a bracket element having a pair o tapered sockets', apair of hanger bars 'having rlgidly formed tapered projections bearin in said sockets, and means for automatical y taking up the wear of the bearings.

' 10. A brake hanger device, comprising a Ibracket element having a pair of tapered sockets, a pair of hanger bars having rigidly formed tapered projections bearing in said sockets, and a spring mechanism acting to force thetapered projections into the sockets.

In testimony whereof I have hereunto set i my hand.
